DynamicTablesPkg: Add AmlLib OperationRegion code generator

Add AmlCodeGenOperationRegion() to create an AML OperationRegion
object from a region name, address space, integer offset, and integer
length.

The API creates the OperationRegion object and populates its four fixed
AML operands:

  - RegionName
  - RegionSpace
  - RegionOffset
  - RegionLength

RegionOffset and RegionLength are encoded using the smallest suitable
AML integer representation. The generated node can either be attached
directly to a supplied parent or returned to the caller for later use.

For example, the API can generate an object equivalent to:

  OperationRegion (
    REG0,
    SystemMemory,
    RegionOffset,
    RegionLength
    )

This provides generators with a reusable way to describe register
regions without relying on a precompiled ASL template.
